BACKGROUND OF THE INVENTION

The most environmentally safe way to dispose of pet waste is through acity's waste treatment facilities where it can be processedappropriately. Currently, most methods of getting the pet waste into thesewer systems involves human interaction with the waste namely pickingup the pet waste by hand, which is undesirable and may have sanitaryrelated issues.

The present invention seeks to provide a solution to this problem byproviding a pet waste disposal system that deposits pet waste directlyinto the sewer system without any human interaction or the need to pickthe pet waste up by hand or any handheld or hand operated device. In usethe pet eliminates directly onto an artificial turf that is fashionedinto a belt and mounted on rollers. When the turf belt is rotatedpreferably by a motorized gear system, the pet waste is dropped into acollection basin and then flushed with sprayers into a pipe which isconnected to an existing sewer system. The underside of the turf belt iscleaned with sprayers inside the basin. The system is designed foroutdoor or indoor use, in commercial or residential settings.

SUMMARY OF THE INVENTION

Briefly, the present invention comprises a pet waste disposal apparatusthat includes a waterproof open top container having a first end, asecond end, a pair of sidewalls. Located within the waterproof open topcontainer is a floor surface sloping from the first end to the secondend of the open top container. An outlet drain located on the second endof the open top container connects the floor surface to an existingsewer line for receiving pet waste from the open top containertherethrough.

The pet waste disposal apparatus also includes a pair of spaced apartsupport bars located within the open top container and connecting theside walls of the open top container and a water and weather proofwalking board having a first end, a second end and a top surface. Thewalking board is fixedly supported on the pair of support bars betweenthe pair of sidewalls of the open top container. The pet waste disposalapparatus also includes a first electrically driven roller locatedbetween the first end of the walking board and the first end of the opentop container and supported at least partially within the open topcontainer by the pair of the walls and a second electrically drivenroller located between the second end of the walking board and thesecond end of the open top container and supported at least partiallywithin the open top container by the pair of the walls.

The pet waste disposal apparatus further includes a rotating belt havinga waterproof artificial turf exterior surface and an interior surfaceand is tensioned mounted to the pet waste disposal apparatus by theengagement of the inner interior surface of the rotating belt to theexterior surfaces of the first and second electrically driven rollersand the top surface of the walking board. Located between the firstroller and the first end of the open top container is a pet waste inletfor receiving pet waste from the waterproof artificial turf exteriorsurface when pet waste disposal apparatus is in use.

The pet waste disposal apparatus also includes an electrically drivencover plate mounted proximal the first end of the open top container andmoveable in an angular direction between a closed position and an openedposition to allow the pet waste inlet to receive pet waste from therotating belt into the open top container and a spray cleaning systemlocated within the open top container with the spray cleaning systemhaving at least one sprayer for cleaning the waterproof artificial turfexterior surface of the rotating belt of pet wastes while simultaneouslydirecting pet wastes located on the floor surface of the containerthrough the outlet of the open top container and at least one motor forpowering at least one of electrically driven rollers, the electricallydriven cover plate, and the spray cleaning system.

In the general operation of pet waste disposal apparatus 10, pets suchas canines will defecate on the waterproof artificial turf exteriorsurface 24 of rotating belt 23. A signal will be sent to motor 32 suchas by control system 33 to rotate the electrically driven rollers 18, 20resulting in the rotation of rotating belt 23. The rotation of rotatingbelt 23 will in turn signal for the angular movement of electricallydriven cover plate 26 from a closed position to an opened position toallow the pet waste inlet 22 to receive pet waste 28 dropped from therotating belt 23 into the open top container 11 for pet wastecollection. In order to clean off any residue pet waste that did notdrop from rotating belt 23 spray cleaning system 29 is activated, whichpowers rotating belt cleaning sprayer 30 to shoot a continuous jetstream of water or a combined water and cleaning solution at thewaterproof artificial turf exterior surface 24 of the rotating belt 23to remove any remaining pet waste from waterproof artificial turfexterior surface 24. The floor surface cleaning sprayer 31 of spraycleaning system 29 is also activated to shoot a jet stream of water orcombined water and cleaning solution at the V-shaped floor surface 12 ofthe open top container 11 to simultaneously direct pet waste 28 locatedon the V-shaped floor surface 12 of the open top container 11 throughthe drain outlet 13 of the open top container 11 and into the existingsewer pipe 14 to facilitate the transfer of pet waste collected withinthe open top container 11 to the waste treatment facilities.
